Event Generation for the Large Hadron Collider

• Bryan Webber (U. Cambridge)

Tests of the Standard Model and searches for new phenomena at the LHC depend heavily on computer simulations of signal and background processes. Monte Carlo event generators aim to simulate the final states of high-energy collisions in full detail, down to the level of individual stable particles. I will review the physics behind these programs, their main ingredients and theoretical status, with emphasis on recent work to improve their precision, especially for top-quark and Higgs physics. There will be extensive comparisons with the latest data and predictions for the next LHC run.

Some Aspects of Higgs Physics, after July 2012

Top physics after Higgs boson discovery

• Michael Spannowsky (U. Durham)

In this talk, aimed at PhD students and postdocs, I will argue that after the discovery of a very Standard-Model-like scalar resonance the top quark is the most exciting particle in the Standard Model. It couples to all Standard Model gauge bosons and is integral to the so-called Hierarchy problem. While the LHC was built to discover and study the Higgs boson, it is by construction a top quark factory. With the large amount of data at high energies being collected within the coming years precision studies of the top quark can guide the way to extensions of the Standard Model.

The Higgs Boson

• Tilman Plehn (U. Heidelberg)

After only two years of running the ATLAS and CMS experiments have delivered on the main task of the LHC program: the discovery of a Higgs boson arising from the spontaneous breaking of the electroweak symmetry, as proposed almost 50 years ago. I will introduce the Higgs mechanism and illustrate its role in the Standard Model of particle physics and discuss what constitutes the `discovery'. Since July 4th 2012 the LHC experiments have studied many facets of this new particle, leading CERN to move from the official categorization as `Higgs-like particle' to `Standard-Model-like Higgs particle'. I will discuss which tests and measurements are in the focus of such studies, what the impact of theoretical physics is, and what theorists expect from the LHC once it starts up again with almost twice its previous energy.

Mass hierarchy and physics beyond the Standard Model

ILC Main Linac accelerator development

• Hitoshi (A) Hayano (KEK)

The main part of the ILC accelerator is 11km + 11km Superconducting Main Linac for electron, positron acceleration. The key technology is the use of RF superconductivity to make efficient power transfer from the microwave to the beams. The seminar describe the design, issues and the solutions to make ILC accelerator realize with very low-cost.

The search for the Higgs, it's discovery and measurement of its properties with the Atlas detector at the LHC.

Discussion

Effective Lagrangian for the Higgs

• Adam Falkowski (Université de Paris-Sud)

I will discuss a general effective theory framework to describe the Higgs couplings to the rest of the standard model. Then I will present the up-to-date constraints on the parameters of the effective lagrangian derived from the existing Higgs data and from electroweak precision tests.
